SPECIFICATION forming part of Letters Patent No. 384,412, dated June 12,1883.

Application filed September 27, 1886. Serial No.2l4fil9. (No model.)Patented in France December 5,185..1No. 172,729; in Belgium September 6,1886, No. 74,462, and in England September 7, IBM}, No. 11.390.

To aZZ whom it may concern:

Be it known that we, GERMAIN BAPST and LUGIEN FALIZE, Fils, ofParis,.France, have invented an Improved Alarm for Vfatches and Clocks,of which the'following is a speci fication.

Letters Patent have been granted to us for,

. upon by suitable means to causethe plate to be vibrated, and therebyproduce a rattling or clatteriug sound of great intensity,

In the drawings, Figure 1 is a section and elevation of the plate in adishing-form. Fig.

I 2 shows by a section and elevation a fiat plate secured in a frame.Fig. 3 shows sectional views representing an electro-maguet as the meansfor vibrating the plate. Fig. 4. is an elevation showing a toothed wheelas the means for vibrating the plate.' Fig. 5 is av sectional view ofpart of a clock fitted with the sonorous alarm. Fig. 6 is an invertedplan ofa portion of the base of said clock. Fig. 7 is a section of theflexible plate and elevation of its actuating 'wheel as arranged for awatch. Fig. 8 is a plan of the parts shown in Fig. 7. Fig. 9 is anelevation of the exterior of a clock, showing the movable bezel and thehand for setting the alarm. Fig. 10 is an elevation, partly in section,of a Watch fitted with-onralarm. Fig. 11. is a section at about the linem a: of Fig. 10. Fig. 12 is an elevation of the tubularnrbor thatcarries the hand for setting the alarm. Fig. 13. is a view of a portionof the bezel of the watch or clock. 14 isnn clevationofthe disk andarbor ofthe hand for setting the alarm.

In Figs. 10 and 11 only portions of the ti me- ,m'overnent are shown, soas to represent the more important parts with greater clcarness. Thesefigures are in larger size.

As our invention is especially applicable to time-pieces, we willdescribe it with reference thereto.

E is the watch-case ring orcenter, and. F the inner and G the outer caseat the back of the watch. These two cases are hinged to the ring E, asusual. The spring-barrcl of the timemovement is shown by dot-ted linesat H, Fig. 10, and the teeth upon said spring-barrel gear with thepinion I upon the tubular urbor J, that carries the center wheel, K, andthis wheel K gives movement to the usual train oi gearing leading to theescapcment.

Within the tubular arbor J is the arbor L, carrying the minute-hand M,and loose upon said arbor is a tubular arbor, N, having ntits outer endthe hour-hand O and at its inner end the wheel I. This hour-hand O andwheel]? are revolved once in every twelve hours through the wheels P, Q,and it.

The spring-barrel of the alarm-movement is represented by dotted linesat S, Fig. 10, and said barrel gives movement to the fly 1 through thepinions and wheels 2, 8, 4, 5, 6, 7, and S.

b is a pinion gearing directly with the spring barrel S.

c is a plate of thin sheet metal secured at its 7 edge to a circularrib, V upon the inner back face of the case F, and a is a fingerprojecting from said plate, and with its free end passing in between twoteeth of the pinion Z). If the free end of this pin is moved and thenreleased, a vibration of the pin from 0 to o is produced, as illustratedin Fig. 2, and this vibration is communicated to the plate 0, therebyproducing sound-waves of great intensity.

vibrating the sonorous plate 0, and we will now describe the means forreleasing the toothed wheel at the proper time for vibrating thesonorous plate and sounding the alarm.

12 is a tubular arbor concentric with the arbors of the hour and minutehands, and this arbor is fitted to turn within an opening in thedial-plate 18, and is held to said dial with a slight friction by aclamping nut or rim, 1%. Upon the inner end of said arbor 12 is a. disk,24, having a V-shaped groove, 28, in its face, and at the outer end ofsaid arbor is the hand 18 for setting the alarm.

19 is a V-shapcd pin upon the wheel Rand this pin is kept in contactwith tin: taceot' the l disk 24 by a spring, 20, that bears against/saidwheel P. Atthe outer and free end of the 2o in Fig. 1

At the same time the spring 20 car-1 ries the pin 21- away from thefly T,-releasing the latter, and the pinion bis at onces'et 'i'n;

Figs. '7 S,10, and 11; butiin clocks the-wheelb may be in a plane atv right anglesgto that of the disks, as seen inFig. 5. In Fig. 5 the sonorous' plate is bei neath'an opening in aplate, A, and is clamped to-said plateby aring, b, screwed into aflange,

fa'", upon'said plate A.

The plate c may-'be slightly dishing, asin Fig. 1', and it may be ofwood, metal, glass, or I of any material t-hatca'n be vibrated, and it"5o may be vibrated by an'electro-magnetbrought into actio'n at theproper time by time mechan-ism, or by the opening or closing of a cir-.cu'it, as in burglar or other alarms.
